It looks like there is probably not enough liquid, so it did not really work without agar and I went on with the standard medium and started to figure out how I can control the bacteria (see experiment further | It looks like there is probably not enough liquid, so it did not really work without agar and I went on with the standard medium and started to figure out how I can control the bacteria (see experiment further below) | ||

When I had a little more knowledge I also tried to let grow two extracted bacteria on two different parts on the drawing. I used some darker, blue bacteria for the mushroom (1) and some green/white looking ones for the surrounding (2). | When I had a little more knowledge I also tried to let grow two extracted bacteria on two different parts on the drawing.

So how you can see, the bacteria does not absorb the color. That's probably because there are two different kind of bacteria, one whose cell wall allows it to absorb color, and the other one doesn`t. | |||

It looks like that the bacteria is growing much faster on the part of the medium, where there is no ink. But also where the ink is there are growing bacteria. | It looks like that the bacteria is growing much faster on the part of the medium, where there is no ink.

It also seems like they are soaking in the color. | It also seems like they are soaking in the color. | ||
